The “show interface” command on a Cisco IOS router or switch gives you a lot of information. Here’s an example:R1#show interfaces FastEthernet 0/0FastEthernet0/0 is up, line protocol is up Hardware is Gt96k FE, address is c201.1d00.0000 (bia c201.1d00.0000) MTU 1500 bytes, BW 100000 Kbit/sec, DLY 1000 usec, reliability 255/255, txload 1/255, rxload 1/255 Encapsulation ARPA, loopback not set Keepalive set (10 sec) Full-duplex, 100Mb/s, 100BaseTX/FX ARP type: ARPA, ARP Timeout 04:00:00 Last input never, output 00:00:02, output hang never Last clearing of "show interface" counters never Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0 Queueing strategy: fifo Output queue: 0/40 (size/max) 5 minute input rate 0 bits/sec, 0 packets/sec 5 minute output rate 0 bits/sec, 0 packets/sec 0 packets input, 0 bytes Received 0 broadcasts, 0 runts, 0 giants, 0 throttles 0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored 0 watchdog 0 input packets with dribble condition detected 2 packets output, 403 bytes, 0 underruns 0 output errors, 0 collisions, 1 interface resets 0 unknown protocol drops 0 babbles, 0 late collision, 0 deferred 0 lost carrier, 0 no carrier 0 output buffer failures, 0 output buffers swapped outThere are a number of things we can check with the show interfaces command. Let me describe them:FastEthernet/0 is up, line protocol is up: this means that the interface is physically up and that the protocol is operational. When you use Ethernet, the protocol is normally up unless you configured port-security or BPDU guard. When a violation occurs, you

This is because the speed at both ends is 100Mbps. Configuring Maximum Interface Starting from Release 24.1.1, the N540-24Q8L2DD-SYS router supports up to 1.1Tbps speed. Following are few sample configuration combinations that will help to achieve upto 1.1Tbps speed: 3x100GE + 32x25GE interfaces 3x100GE + 31x25GE + 1x10GE interfaces 4x100GE + 24x25GE + 8x10GE interfaces 4x100GE + 28x25GE interfaces Before the Release 24.1.1, the N540-24Q8L2DD-SYS router supports up to 1Tbps speed. This speed can be achieved with a default combination of 2x100GE + 32x25GE interfaces. Ports with high speed bandwidth allows support for lower speed transceivers. Figure 1. N540-24Q8L2DD-SYS Router Supports up to 1Tbps Apart from the default combination, to support higher speed bandwidth on the interfaces, you need to reconfigure the controllers so that the maximum speed is still within 1Tbps.

In a Sparkplug MQTT network there is no direct link between end nodes and the primary application (control node).All communication between nodes is via a central MQTT server.In this tutorial we will look at the message payloads and how the various components establish a session with the MQTT broker and what they publish.A diagram of a Sparkplug network is shown below for reference.Sparkplug Payload BasicsThe Sparkplug payload uses Google Protocol buffers which is a way of representing complex data as a string and functions in a similar way to JSON.Google Protocol buffersare more complex than JSON, but that complexity is taken care of in libraries which are available for all major languages.A Sparkplug payload contains a series of metrics (readings). The metric has a:NameAliasTime stampData typeValueBelow is an example taken from a EON birth message (NBIRTH)Note: The alias published in the metric can be used in place of the name in subsequent messages.All messages published have a sequence number starting at 0 and ending at 255 after which it is reset to 0.All messages include a time stamp for the message and also a time stamp for each metric in the message.Data Types aren’t part of the Sparkplug B specification but are defined in the client libraries. A numeric code is assigned to the data type.Below shows the python client library data type declaration.Sparkplug Message BasicsThere are five basic message types:BirthDeathDataCommandStateThe content of these messages varies by message type. The required components of each message type are detailed in the section 16 of the specification.Below is a screen shot taken from the specification for a NDATA message.How Sparkplug Components CommunicateAs shown in the diagram above we have several components in a Sparkplug system. There are:Primary applicationEON (Edge of Network) nodesDevice NodesIn this section we look at the messages and message payloads that are exchanged by these nodes.Primary Application Session Establishment and MessagesWhen the control application comes online it publishes:Last Will messageBirth MessageThe topic used is STATE/scada_host_id and the payload format is a simple UTF-8 string and does not use the standard Google protocol buffers format used by other messages.The last
